I think I ordered some 6.5X55 from them that was labeled practice/dummy and had wood bullets. I didn't intend to shoot it and have never tried, but I assumed it has a primer or something firing it. Maybe totally different product, maybe mine doesn't have any propellant, but I can't imagine there are a whole lot of surplus training ammo types for 6.5 X55. I never looked at mine closely. They were dirt cheap and kind of cool looking/sounding so I bought a few.
